Three Dimensional Imaging in Nuclei.
ORAL
Abstract
We perform the first simultaneous global QCD extraction of the transverse momentum dependent (TMD) Parton Distribution Functions in nuclei and the nuclear modified TMD Fragmentation Functions, which encode the three-dimensional information on the partonic structure of nuclei, and hadron formation in a nuclear medium, respectively. This analysis takes into account the world data from semi-inclusive electron-nucleus deep inelastic scattering and Drell-Yan di-lepton production in proton-nucleus collisions, comprising a total of 126 data points from 6 data sets with chi^2/dof = 1.045. We quantify for the first time the broadening of partonic distributions in nuclei comparing with those in free nucleons. We also make predictions for the ongoing JLab 12 GeV program and future EIC measurements, which will further constrain the three-dimensional partonic structure of nuclei.
